Statement 1 is not correct: Moon’s interior is dynamic: Findings from Chandrayan 1 also showed
that the Moon’s interior was dynamic and interacted with the exosphere, contrary to the belief
that it was dormant.
- The terrain mapping camera found evidence of volcanic vent, lava pond, and lava channels as recent as 100 million years old, indicating recent volcanic activity.
- Measurements of carbon dioxide by the MIP also pointed towards de-gassing from the surface. This shows an interaction of the lunar surface with the exosphere even in the absence of impacts by meteors.
Statement 2 is correct: Distribution of gas in lunar atmosphere: Chandrayaan 2 confirmed that the Argon-40 (Ar-40) exists in the lunar exosphere but the knowledge of its distribution at higher latitudes was lacking. The findings were crucial for developing insights into the dynamics of the lunar exosphere.
Statement 3 is correct: Mission experiments of Chandrayaan 3. The lander has four experiments
on board.
- Study of the electrons and ions near the surface of the moon and how they change over time.
- The thermal properties of the lunar surface near the polar region. Chandrayaan-3 has landed around 70 degree south latitude, the closest that any spacecraft has reached to the lunar south pole.
- To measure the lunar quakes near the landing site and study the composition of the Moon’s crust and mantle.
- The LASER Retroreflector Array (LRA) is a passive experiment sent by NASA that acts as a target for lasers for very accurate measurements for future missions.
